Complete My "home Work" Assignment For My A-Level Computing?
Feb 4, 2009
I'm not looking for anyone to complete my "home work" assignment for my A-Level computing as I've done this now and I think it's impressive. What I am now looking for is help in extending what I have done and making it better.
History:I have built my application in Visual Basic 2005 Express Edition. It is a Console Application. After filling in the questionnaire the user gets given results and all this information is stored in a .txt document (Notepad). I want the data that is put in to the application to send infomation to the user's e-mail address. I have been looking around the internet and it says it could do it but it needs Outlook express.

I have been given the prep material for my AS Level (Year 12) computer programming exam based around dice cricket. Written in VB 2008.
In the exam we are supposed to change bits based upon the scenario. The scenario and skeleton code are attached.
I have looked through the code so far and made some guesses to what I think may be on the test:
[code...]
if there is anything I am missing which they think I could be asked on the test. I then have to go away and figure out how to program.
So by asking on here, I am not trying to find out coding answers - I do want to figure that out myself. I just want to see if there is anything else I possibly could be asked?

I have just started coding my Computing project for my A-Level, and I will admit, I am far more experienced in VB6 than VB.NET (as embarrassing as that is to say).I get extra marks for making everything presentable, so was wondering if it was possible to add icons into .NET buttons. For example if I have a button to add an entry to the database, I want a nice Web 2.0 looking icon (for which I already have) next to the text on that button.

I have a program originally compiled in VS2008 on a WindowsXP Pro box. The program uses Microsoft DAO 3.5 Object Library to access an Access database.
When I try and run the program on Windows XP (any version) it runs just fine. If I try and run in on Vista (any version) it doesn't work. When I try and run it on Windows 7 Pro, it runs fine. I really want it to run on Windows 7 Home Premium, but I get an interop error anytime I try and access the database.

While DataReader.Read
Dim Foo as New FooBar
Foo.Property = "Test"
Loop
In VB.net, does this create a new Foo instance every for every loop? Or just one Foo instance with block level scope? Do all blocks (If..EndIf, For..Next) work the same in this regard?

I am creating an Excel add-in written in VB.NET. I would like to bind KeyDown and KeyUp events to the spreadsheet to record when the user presses and releases the arrow keys while navigating the spreadsheetIdeally, these events would be built into Excel alongside the native SheetActivate and SheetSelectionChange events, for example. Alas, they are not.

I have created a simple program which uses a two tier structure of SQL Tables.At the top level, one record holds the date of the activities and linked to it using its primary key as a foreign key, three subordinate tables hold time stamped records.The issue I have been unable to solve is that before adding any of the lower level records for a given date, a newly added top level record must be saved to the database.Doing this manually is simple - but can I rely on my users to remember to do this before they start plugging in the lower level data?I thought not, so I am looking to save the top level automatically.I've failed miserably but I refuse to believe that it's not possible.

I'm trying to compute 100! and there doesn't seem to be a built-in factorial function. So, I've written:
Protected Sub ComputeFactorial(ByVal n As ULong)
Dim factorial As ULong = 1
Dim i As Integer
For i = 1 To n
[code]....
Unfortunately, running this with the value of 100 for n rseults in
Value was either too large or too small for a UInt64.
So, is there a larger data type for holding numbers? Am i mistaken in my methods?

I love to experiment with linqpad, but now my task requires heavy computing power. Trying to do it on my computer is painful. My friend has a much more powerful computer than I -- can I execute some operations from my linqpad on his computer? I don't have RDP access, but I can run any .NET program on his computer.
If it is not possible, then is there any FREE service that provides computing power? Maybe a hosting trial or something. I know that Windows Azure offers a 30-day trial, but it has a very slow CPU module and in my country, MS partners cannot be expected to fix service sites when they go down.

How would you take a numerical input from 10 text boxes and total it up and send it to a label. Then average the 10 numeric text boxes and send it to its own label. I am not asking for any code, I just need a hint or two to jog my memory. If this is not clear for you, I'll provide more detail.

I have multiple level of For Each and in each level, i have a Linq that is the 'In' criteria as in:
[Code]....
It will go inside each for (because the value is not nothing), however, it will only loop (next) in the very inner 'For Each t In tFor'. After it is finish inner loops, the outer Fors' or Next will not execute... even thought there are more than one values in that 'In'... like 'sFor' or 'fFor'. i've noticed while debuging, while break at the for (for example 'sFor', before stepping in), i get the error message:
"Enumeration yielded no results" when i expand the result for that variable and it will not step into it. but if i do not expand the result, it will step in. It seem that some how, once an element is accessed for that 'In' collection, it breaks (meaning does not loop for the rest of the elements) the next for that collection is this a bug or am i missing something in Linq? BTW: i believe it has something to do with the SqlDataReader in the Linq. I'm working with IAsyncResult.

I've had experience with using hashvalues from String objects. E.g., if I have StringA and StringB both equal to "foo", they'll both compute out the same hashvalue, because they're set to equal values. Now what if I have a List, with T being a native data type. If I tried to compute the hashvalue of ListA and ListB, assuming that they'd both be the same size and contain the same information, wouldn't they have equal hashvalues as well?
Assuming as sample dataset of 'byte' with a length of 5
{5,2,0,1,3}

I am trying to write code to compute the Efield on a point P in both the x and y direction, from a charged ring. double y_eField = (_ke_value * _dq * (Sin_angle) / (Math.Pow(r, r)));Problem I am having is the code seems to follow the equation as given but the result it outputs is not correct at all.

I have a server that runs a thread that computes some data through function X. Then I have a client that communicates with the server and gets results from function Y. Now, both function (X and Y) share a common variable lets say varZ. When function X populates varZ when the thread starts on the server, the results are not propagated on function Y when accessed by the client through Remoting. But on the server side the results are correct in function Y! It's almost like when client calls function Y, it has no idea what is happening varZ is as far as the value set by function X thread in the server.

I need to create an console application that computes the average monthly rainfall, number of months with above average rainfall, and the number of months with below average rainfall, given the rainfall amounts for each month in a particular year. The program must read in and store in an array the monthly rainfall amounts entered by the user one by one.
So far this is what I have got
Const intMonths As Integer = 11 'Constant Month variable
Dim sngRainfall(intMonths) As Single 'Rain for the month
Dim intCount As Integer ' Loop Counter
Dim sngTotalRainfall, sngAvgRainfall As Single 'Total and Average Rainfall
[Code] .....
How to set this up properly and I am having a real hard time figuring out how to make the data go from this loop to another and add the data to the total.

For example i wanna built some VB.net program that i use from Office which sends signal/Message to the PC running at Home(There will be a VB.net program at HOME pc also which is always waiting for the incoming messages) and gets the response from that PC at home.
In General i want that my program(vb.net) at Office communicates with my Program(vb.net) at home even if there is nobody at home, so that i can share some files or may be perform some other operations at home pc even if i m away.
